What this line sorter does

It reorganizes one-line-per-item text using alphabetical, natural, numerical, length or random ordering, with optional trimming and deduplication.

How to use it

• Enter one item per line.
• Choose a mode and locale.
• Set case, trim, empty-line or duplicate options.
• Copy, download or replace the source with the result.

Practical example

Input: item10, item2, item1
Natural output: item1, item2, item10

Methodology

Alphabetical and natural modes use Intl.Collator. Numeric mode retains invalid numeric lines after valid numbers. Shuffle uses an in-place Fisher–Yates algorithm.

Common uses and mistakes

• Ordering product or task lists
• Sorting version-like labels naturally
• Sorting numeric exports
• Accidentally trimming meaningful indentation

Limitations

Locale identifiers depend on browser support. Numerical mode accepts JavaScript finite-number syntax and does not parse currency-formatted values. Empty-line positions are not preserved when sorting.
